A universal health care system? Unmet need for medical care

among regular and irregular immigrants in Italy

Annalisa Busetta1, Valeria Cetorelli2 and Ben Wilson3,4

Abstract

Italy has a universal health care system that covers, in principle, the whole resident population,

irrespective of citizenship and legal status. This study calculates the prevalence of unmet need for

medical care among Italian citizens, regular and irregular immigrants and estimates logistic regression

models to assess whether differences by citizenship and legal status hold true once adjusting for

potential confounders. The analysis is based on two Surveys on Income and Living Conditions of

Italian households and households with foreigners. Controlling for various factors, the odds of

experiencing unmet need for medical care are 27% higher for regular immigrants than for Italian

citizens and 59% higher for irregular immigrants. The gaps by citizenship and legal status are even

more striking among those with chronic illnesses. These results reveal the high vulnerability of

immigrants in Italy and the need to develop more effective policies to achieve health care access for

all residents.

Introduction

The Italian public universal health care system covers - in principle - the whole resident population,

irrespective of citizenship and legal status. As such, it is classified as one of the most inclusive health

care systems in Europe [1-3]. Health as a right for all is explicitly recognised in article 32 of the Italian

Constitution, according to which “The Republic safeguards health as a fundamental right of the

individual and as a collective interest, and guarantees free medical care to the indigent”.

Despite this fact, there are significant inequalities in access to medical care. There is a higher

prevalence of unmet need for medical care for those who have a low income [4], and geographical

disparities in access to medical care have been exacerbated in the last two decades by the progressive

decentralisation of health services to regional administrations [5].

Inequality in access to medical care between citizens and immigrants is a phenomenon of

growing importance in Italy [6-9]. Immigrants seem to experience specific barriers to medical care,

which are in addition to existing economic and geographical inequalities [10]. Some studies have

argued that social class is the underlying determinant of this inequality [6], while others have

contended that ethnic discrimination compounds economic deprivation [7,11]. The concept of social

capital has also been used in explaining immigrants’ additional obstacles to accessing medical care

compared to the Italian population [12]. Lack of knowledge about national laws and administrative

regulations may limit immigrants’ ability to access health services, while language difficulties and

cultural factors may also represent serious barriers to access [13,14].

Unmet need for medical care may be related to socio-demographic characteristics and health

profiles. The international literature has shown that after an initial “healthy immigrant effect” - owing

to a self-selection process prior to migration - immigrants’ health tends to deteriorate with the time

spent in the host country, and this results in an increased need for medical care [15-17]. The worsening

health conditions after resettlements have been attributed to health-impairing work environments,

inadequate salaries, poor housing, as well as real and perceived social exclusion [18]. This is

increasingly the case in Italy, where the health profiles of immigrants have significantly deteriorated

over the last decade [19].

Little is known, however, about the links between health care access and legal immigration

status. Immigrants in an irregular situation - i.e. those who do not fulfil conditions for entry or stay in

the country - constitute a particularly vulnerable group because they are more likely to be subjected to

exploitative working conditions and precarious housing [2]. Typically, they are also fearful that their

irregular status could be reported to the migration authorities, are largely unaware of their rights, and

often suffer from hostile and discriminatory attitudes [2]. The health of irregular immigrants is of

particular concern with respect to chronic illnesses such as respiratory disease, high blood pressure,

cardiovascular disease, diabetes, and cancer, as well as health problems arising from hard

living/working conditions, unhealthy lifestyles, and a lack of adequate access to preventive care.

Furthermore, their precarious situation makes continuity of care especially difficult [2].

To date no study has been carried out to quantify the extent of unmet need for medical care in

Italy by legal status. The present paper fills this knowledge gap and contributes to the growing body of

research on health inequities by assessing differences in unmet need for medical care between Italian

citizens, regular and irregular immigrants. The aim is to show whether differences exist, and whether

they remain after adjusting for socio-demographic characteristics, subjective health, poverty measures,

and geographical residence. We also examine whether the differential unmet need by legal status

widens in case of chronic illnesses that require long-term continuous care, and the extent to which our

findings are different for male and female immigrants. The importance of our results is not limited to

the Italian context as they provide useful insights for the health protection of regular and irregular

immigrants in other European countries who, like Italy, are currently experiencing sustained

immigration flows, including the onward flow of non-Italian immigrants from Italy.

Methods

This study is based on merged data from the 2009 standard Italian Survey on Income and Living

Conditions (SILC) and the 2009 special Italian Survey on Income and Living Conditions of

households with foreigners. Both surveys were conducted by the Italian National Institute for Statistics

(Istat), they used the same methodological tools (questionnaires, survey techniques, methods of

correction, imputation and integration of data, etc.), covered the same time period, and interviewed all

individuals aged 16 and over living in the selected households.

The standard Italian SILC was carried out on individuals living in about 26,000 households

selected with a standard two-stage stratified sampling design typically used by Istat in face-to-face

household surveys representative of the Italian population [20]. The special SILC is the largest survey

of the immigrant population ever conducted in Italy, covering over 6,000 households with at least one

foreign member. The sampling techniques took into account the size of different foreign-national

groups and their geographical distribution across the country [21]. All interviewees were asked about

their legal status; those who reported no regular resident permit constituted more than 17% of the

sample. As asserted by Istat, the sample of households with at least one foreigner members from the

special SILC survey is comparable with that of households made up exclusively of Italians from the

standard SILC survey.

Besides collecting a wide range of socio-demographic and economic variables, both surveys

included a series of questions about health. Unmet need for medical care was assessed using the

following question: “During the last 12 months, was there ever a time when you felt you needed a

medical examination or treatment for a health problem but you did not receive it?”. Interviewees who

replied affirmatively were considered to have experienced unmet need.

Our analytical sample includes 43,636 Italian citizens, 8,133 immigrants with a regular

resident permit, and 1,704 immigrants who are classified as irregular. This classification is based on a

question which asks immigrants whether they have a residence permit or a visa. The question includes

different response options to account for the variation in residence requirements for different

immigrant groups. All non-EU foreigners require a resident permit or a visa to reside in Italy

regularly, and although EU foreigners can circulate in Italy without any restriction, they are also

required to register their residence if they stay in Italy for more than 3 months. In order to be classified

as ‘regular’ in our analysis, this implies (in almost all cases) that immigrants either have a job, are

studying full-time, are a legal partner of a legal resident, or can demonstrate that they have enough

money to qualify for health insurance.

We calculate the prevalence of unmet need for medical care separately for Italian citizens,

regular and irregular immigrants. Next, we estimate logistic regression models to assess whether

differences by legal status hold true after controlling for potential confounders such as sex, age,

education, labour force participation, self-assessed health, and self-rated poverty. A regional variable

is also included to account for geographical disparities in supply and quality of health services. We run

the analysis on the whole sample and on the sub-sample of those who reported suffering from chronic

illnesses. We conclude by repeating the analysis separately for male and female immigrants, excluding

citizens, which shows how the differential in unmet need for medical care varies by sex when

comparing regular and irregular immigrants.

Results

Overall, around 7% of individuals in the sample reported to have experienced unmet need for medical

care during the last 12 months. Differences by legal status are notable: the prevalence of unmet need is

7% among Italian citizens, 8% among regular immigrants, and 11% among irregular immigrants.

Unmet need for medical care is higher for the sub-sample with chronic illnesses, and differences by

legal status are more substantial: the prevalence is 12% among Italian citizens, 20% among regular

immigrants and 32% among irregular immigrants (see figure 1).

Table 1 shows the results from two logistic regression models for the association between

legal status and the odds of experiencing unmet need for medical care. Model 1 refers to the whole

sample, and Model 2 only to the sub-sample of those suffering from chronic illnesses. Both models

control for self-rated health, self-assessed poverty, socio-demographic characteristics, and region of

residence.

After adjusting for potential confounders, there are still significant differences in access to

healthcare by legal status. For both regular and irregular immigrants, the odds of having unmet need

for medical care are significantly higher than Italian citizens, and the size of this differential is even

higher for those with chronic illness.

Immigrants with a regular resident permit are more likely to experience unmet need for

medical care than Italian citizens (Odds ratio, OR = 1.27), and immigrants in an irregular situation are

even more likely to experience unmet need than Italian citizens (OR = 1.59). For the sub-sample of

those suffering from chronic illnesses, legal status is an even a stronger predictor of unmet need for

medical care. The differences are striking: the odds of experiencing unmet need for medical care are

1.4 times higher for regular immigrants with a chronic illness as compared with Italian citizens who

have a chronic illness, and 2.5 times higher for irregular immigrants.

In both models, there is a strong health gradient, whereby individuals with poorer subjective

health are progressively more likely to experience barriers to accessing medical care. In particular, the

odds of experiencing unmet need for those with very bad self-rated health are around 8 times higher

than for those who declare very good health, in the model including the whole sample, and 4.5 times

higher in the model restricted to those with chronic illness.

As widely documented in Italy, and elsewhere in Europe, we find that one of the main

determinants of unmet need for medical care is poor living conditions [23,26,27]. Our model shows

that better off individuals are progressively less likely to experience unmet need for medical care when

compared to those who report ‘making ends meet’ with great difficulty. Those who have the lowest

self-assessed poverty constitute an exception to the general gradient: although this may be due to the

inability of the public welfare system to satisfy individuals with higher standards of service.

Specific to the Italian context is the large geographical disparity in the odds of experiencing

unmet need, such that individuals living in the centre, and even more so the south, are more likely to

experience barriers to care than those living in the north [5]. Both self-assessed poverty, and region of

residence, remain similarly strong and significant for the sub-sample of those suffering from chronic

illnesses.

Consistent with previous research, we find that the odds of experiencing unmet need for

medical care increase with age by about 4% per year, but slowly decline at older ages [26]. With the

exception of those who have post-secondary education in model 1, education has no significant

(conditional) relationship with unmet need. Similarly, we do not detect any significant difference in

unmet need for medical care between those who are employed, self-employed and unemployed.

Despite this, those who are not in the labour force (i.e. inactive) are significantly less likely to report

having experienced unmet need (in both the overall model and the model for those with chronic

illness).

In our final analysis, we present the results of a focussed comparison between irregular and

regular immigrants. Our analysis is identical to that used to produce table 1, except that we now

exclude Italian citizens and estimate separate models for men and women. This is broadly equivalent

to a full interaction between sex and all other variables. By excluding Italian citizens, we seek to

establish the extent to which irregular immigrants are significantly different from regular immigrants.

The results show that there is a significantly higher unmet need for medical care for irregular

male (versus regular male) immigrants, and that the same is true for females, although to a lesser

extent (see figure 2). For the sub-samples with chronic illness, this difference between men and

women is exacerbated, such that the odds of unmet need are 3 times higher (and significant) for

irregular male immigrants, as compared with regular males. This is in contrast to females with chronic

illness, where the odds ratio is smaller and non-significant.

Discussion

Health as a right for all is a core objective of the Italian public universal health care system. Despite

this, many individuals in Italy experience barriers to accessing medical care due to unaffordability and

unavailability of health services [4,5]. The situation is especially challenging for immigrants, who

often lack knowledge of national laws and administrative regulations, tend to experience cultural and

language difficulties, and suffer from precarious living conditions and social exclusion [2,13,14].

In this paper, we focus on differences in unmet need for medical care between citizens, regular

and irregular immigrants in Italy. Our analysis documents that, other things being equal, there are

considerable disparities in access to care not only between citizens and non-citizens, but also between

regular and irregular immigrants.

Compared to Italian citizens the odds of experiencing unmet need are greater for regular and

irregular immigrants, and these gaps are even more striking for the sub-sample of those suffering from

chronic health conditions. Research in Italy and elsewhere in Europe suggests that chronic illnesses

are becoming a serious concern for both the immigrant and native populations. Our results show that

regular and irregular immigrants with chronic illnesses are much more likely to experience unmet

need for medical care than Italian citizens with similar conditions.

Our results also demonstrate the importance of sex for understanding immigrant inequalities

in unmet need. Table 1 shows that there is a significant gender gap in unmet need for medical care,

with women being more likely to experience barriers accessing care than men. A similar gender gap

has been noted in both public and private health care systems [24,25]. But after excluding Italian

citizens, and making direct comparison between irregular and regular immigrants, the direction of this

association is reversed. Irregular female immigrants are less likely than men to experience unmet

need, especially if they have a chronic illness. One implication of this finding is that policies to reduce

the unmet need for medical care among immigrants must take account of differences between men and

women, and may even benefit from targeting men.

It is important to highlight that our analysis has some limitations due to data availability. First,

the use of the Survey of Income and Living Conditions of households with foreigners (i.e. individuals

living in households with at least one foreign member from population register) means that irregular

immigrants are included in the sample if and only if they live with someone that is in the population

register. This implies the exclusion of some immigrants who have an irregular migration status, in

particular those who are living in camps, are homeless, or have no stable residence. Given that these

immigrants may be even more marginalised than those in our study, we may in fact be

underestimating unmet need. On the other hand, some immigrants will acquire Italian citizenship by

naturalization, or by marriage to an Italian citizen, and if they are less likely than other immigrants to

experience unmet need, then there may be a bias in the other direction.

Another limitation is the cross-sectional nature of the survey. Our cross-sectional data do not

allow for a proper measurement of health status and health access change over time. With these data, it

is not possible to verify if immigrants’ health deteriorates with duration spent in Italy, and if their need

for medical care increases consequently. In particular, it is not possible to verify if immigrants develop

severe chronic illnesses because they lack adequate access to preventive health care services, or to

study other more complex aspects of health selection. Finally, although our data provide information

about immigrant origins and ages at arrival, the heterogeneity across these variables does not allow us

to measure the links between unmet need for medical care and membership of different immigration

cohorts.

Conclusion

This study has revealed the high vulnerability of immigrants in Italy, and the urgent need to develop

more effective policies if the goal of health for all is to be achieved. Culturally-sensitive interventions

should be adopted to promote knowledge about the right to health, in particular among irregular

immigrants. These policies must pay attention to differences between men and women, and in the case

of irregular immigrants with chronic illness, may need to target men. Interventions addressing the

difficult and health-impairing environments in which irregular immigrants often live and work are also

required. More general policies should be oriented towards assisting individuals with a high level of

self-perceived poverty, and towards expanding availability of health services in the central and

southern regions. Finally, more detailed studies on the most vulnerable groups of immigrants are

necessary. These include irregular or regular immigrants (especially asylum seekers and refugees) who

do not have access to medical care (neither general practitioner nor specialist consultations) and do not

have enough economic resources to buy medications at full price in pharmacies.
